Since NIS has no way to know if it is scanning e-mails, I decided to do the Eicar test. I found the file online, diabled NIS, attached eicar to an e-mail, reactivated NIS and sent the e-mail with NIS letting it be sent out. Waited a few seconds and hit "Get Mail" where NIS quickly popped up and said it detected eicar and removed it. i have run this test several times with the very same result. It doesn't get it going out. There is also a box to check that is supposed to show a indicator that the e-mails are being scanned and after testing this repeatedly with very large files, no such indicator shows. I'm so disappointed with Norton I'm considering going back to Avast. I was at first lulled into a false sense of security because I had only checked on incoming mail. It doesn't scan outgoing mail.
